Problems solved by technology

Although this method has achieved the purpose of detasseling to a certain extent, since hundreds of stamens in each flower grow around a pistil, using this method to remove the stamens one by one with tweezers takes a long time and is inefficient. A little inattentive and easy to injure the pistil

Embodiment 1

[0034] The tea tree detasseling method of the present embodiment may further comprise the steps:

[0035] Detasseling tea tree flower buds in the early stage: 1-2 days before the flowering plant of the female parent, select tea tree flower buds with large and full flower buds, white petals, and relatively soft buds.

[0036] Step 1: Gently place the index finger, ring finger and thumb of both hands between the flower stalk and the flower bud, then place the two thumbs on the top of the flower bud (directly above), and grasp the two sides of the flower stalk near the flower bud with the two index fingers and two ring fingers , fix the flower buds on the stalk to ensure that the flower buds will not fall off the flower stalk;

[0037] Step 2: With the thumbnails of both hands, use a little force to break the petals in the middle of the bud to both sides to reveal the stamens, and divide the buds into the side with the pistil and the side without the pistil, so as not to damage t...

Abstract

The invention provides a tea tree stamen removal method for quickly and accurately removing stamens. The method includes steps: step 1, grabbing the top of a flower bud and two sides close to a pedicel of the flower bud; step 2, gently separating petals of the flower bud towards two sides to expose stamens and pistils, and separating the flower bud into one side with the pistils and one side without the pistils; step 3, on the side without the pistils, grabbing roots of the stamens to remove the stamens by twisting; step 4, on the side with the pistils, grabbing more than one stamen close to the pistils to remove the stamens by clockwise or anticlockwise turning around the pistils towards a direction of more stamens.

Description

technical field [0001] The invention relates to the technical field of hybrid breeding methods, in particular to a tea tree detasseling method. Background technique [0002] Heterosis is a common phenomenon in the biological world, and the use of heterosis has become one of the main ways of tea tree breeding. Artificial hybridization of tea trees is time-consuming and labor-intensive, especially manual detasseling requires carefulness and patience. Although tea tree is a cross-pollination crop, it still has a certain self-seed setting rate (generally <4.0%). Therefore, artificial hybridization for the purpose of studying genetic laws must be emasculated. Detasseling of camellias is a heavy work. Since there is no quick method of detasseling, the work is extremely time-consuming and labor-intensive, and requires the staff to be very meticulous. [0003] The Chinese invention patent with the application number 201410118237.X discloses the artificial hybridization petal p...
